I have a 4672 hoe, and was digging some shallow trenches for drainage over the last 2 weekends. I noticed that for the first 15 minutes or so, the hoe is extremely slow and very noisy. The fluid reservoir is between the lines on the dipstick, and the engine is running at the recommended RPM. It seems like tiny air bubbles are being flushed from the rams during warm up.
A important note:
The valve was leaky when I received it, but the hoe worked great (the side 2 side swinging was VERY fast).
I used it to dig out a few stumps and dig one huge hole (10x8x6), and it worked like a charm, but was very messy and needed to be topped off once in a while. I finally got frustrated witht the mess and tightened each hose fitting into the valve body. I only tightened the fittings (not the relief valve setting), but wasn't sure on the torque to use. I could not find a torque spec sheet for these fittings, so I was just using my "feel".
This warm up stuff only began happening since I did that. Any thoughts? is this what happens to hoes after they break in (I've got 64 hours total on the new 2710, with about 25 hours on backhoe work). Oh yeah, I've greased the hoe as indicated.
Please see the relocation of this post to Attachments Backhoe slow and noisy for 20 minutes .
